Fig. S1.

Hand, feet, and motion selectivity occupy distinct cortical regions. (A) Hand (orange), foot (green), and motion selectivity (blue) are viewed on the lateral occipito-temporal cortex in both groups. Hand and foot selectivity are compared on a winner-takes-all approach (each condition is compared with baseline at P < 0.05, FDR corrected, and the preferred body part is then selected for each vertex), revealing an inferior and posterior (dorsal) area, which show a preference for viewing feet over viewing hands in both groups. Motion selectivity was measured with an additional localizer (Materials and Methods; P < 0.05, FDR corrected). Importantly, hands- and feet-preferential responses do not all result from an overlap with motion-selective regions. (B) Hand (orange; hands > feet), foot (green; feet > hands), and motion (blue; moving > stationary rings) selectivity (measured by direct contrast) are depicted in individual subjects, largely reproducing the pattern seen in the group results of having distinct hand and foot preferences, which do not overlap with motion selectivity. For two dysplasic subjects who do not have individual motion selectivity localizers (D2, D3), group motion selectivity data from both groups is presented (in blue and cyan for the control and dysplasic groups, respectively; greatly overlapping with one another).
